Embodiment Construction

[0016] like figure 1 Shown, the armrest of walk-behind harvester of the present invention comprises armrest seat, and armrest seat is fixed on the frame. A handrail branch pipe 1 is fixed on the handrail seat, and the handrail branch pipe 1 is a hollow metal tube, which is generally made by bending a stainless steel pipe. There are two handrail branch pipes 2, which are combined to form a handrail main pipe 2, so that the interior of the handrail main pipe 2 and the handrail branch pipe 1 are the same, forming a structure similar to a three-way pipe. The end of handrail main pipe 2 is sleeved with a corrugated pipe, and this corrugated pipe communicates with the intake pipe of the engine installed on the harvester support. The end cover of armrest branch pipe 1 is provided with an armrest cover 3, and armrest cover 3 is made of rubber material, and is processed with annular anti-skid line on armrest cover 3, prevents the phenomenon that slipping occurs when using. All have a...

Abstract

The present invention discloses a handrail of a walk-behind harvester. Two handrail branch tubes converge to form a handrail main tube, the handrail branch tubes and the handrail main tube are both hollow tubes, tail ends of the handrail branch tubes are sleeved by handrail sleeves, a handrail seat is disposed on the handrail main tube, end faces and circumferential faces of the handrail sleeves are provided with air inlets, the air inlets and the handrail branch tubes are communicated, and an air inlet corrugated pipe communicated with the handrail main tube is fixed at an end part of the handrail main tube. With arrangement of the air inlets in the handrail sleeve, air enters into the handrail branch tubes and the handrail main tube through the air inlets and then into an engine from the air inlet corrugated pipe through the handrail main tube. Because the walk-behind harvester is originally provided with a handrail, the structure of the handrail is not required for extra addition. By using a hollow structure of the conventional handrail, the handrail main tube and the handrail branch tubes of the overall handrail are used as extra air inlet pipes, the air inlet amount of the engine can be raised, and the problem that an air inlet installation structure of the conventional walk-behind harvester is small in space is solved.

Description

technical field [0001] The invention relates to a part of a walk-behind harvester, in particular to an armrest of the walk-behind harvester. Background technique [0002] Harvesters have been developed into integrated machinery for harvesting crops at present. Harvesting, threshing and concentrating the grains into the storage bin at one time, and then transporting the grains to the transport vehicles through the conveyor belt. Manual harvesting can also be used to spread the stalks of rice, wheat and other crops in the field, and then use grain harvesting machinery to pick up and threshing. Crop harvesting machinery for harvesting grains and stalks of cereal crops such as rice and wheat. Including harvesters, windrowers, balers, grain combines and grain threshers, etc. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools. [0003] The walk-behind harvester supports the weight of the tool by the walking wheels, the machine is pus...
